Development of a buffer fence to protect cars from direct collisions with supports.

Accidental collisions with support structures such as utility poles, signposts, and streetlight poles are more likely to be extremely serious than other kinds of accidents. One method of buffering collisions with such structures used in many countries is the breakaway structure that allows a pole to collapse when struck by a vehicle. This method has reduced damage to vehicles and injuries to their occupants caused by these collisions. But this structure is not suitable for narrow roads carrying heavy traffic where a collapsing pole might cause secondary injuries to third parties. This study was undertaken to develop a collision buffer fence (below called a "buffer fence") that prevents a car from directly colliding with a support structure or roadside trees (below called, "support structures") and to reduce injuries to a car's occupants during such a collision for use as a buffer measure for support structures installed beside narrow roads.
